PROFILE

Mikaël Ducharme

Over a three-month period, Marc Ducharme enhanced data orchestration and infrastructure in the mozilla/telemetry-airflow and mozilla/terraform-modules repositories. He migrated and improved Airflow DAGs for monthly data ingestion, leveraging Python and BigQuery to streamline ETL workflows and secure partner data transfers via SFTP. In mozilla/terraform-modules, Marc developed inline alert policy configuration for Google Cloud Monitoring using Terraform and HCL, improving monitoring coverage and deployment transparency. He also simplified repository contribution processes by redesigning PR templates and updating documentation. Marc’s work demonstrated depth in cloud engineering, configuration management, and infrastructure as code, resulting in more reliable, maintainable, and secure systems.

Aug 1, 2025

Month 2025-08: Delivered two major data orchestration improvements in mozilla/telemetry-airflow. Migrated and enhanced the PeopleTeam monthly data DAG from Composer to Airflow, enabling scalable ingestion, staging in BigQuery, and a merge workflow with improved column handling and default operator cleanup. Also introduced the People Integration Data Pipeline (Workday to TripActions) to extract data from Workday, load into BigQuery, and securely transfer to SFTP, with updated secrets and connection IDs. Implemented targeted fixes across both pipelines to enhance reliability, security, and operational simplicity. The work delivers faster, more reliable monthly analytics and stronger data governance for partner integrations.

Summary for April 2025 (mozilla/terraform-modules): Delivered a major feature and fixed documentation to strengthen monitoring capabilities and cost clarity. The Google Cloud Monitoring Uptime Check Alert Policy Configuration adds inline alert policy support to the google_monitoring Terraform module, enabling defined alert conditions, severity, and notification channels for uptime checks. This enhances proactive monitoring, reduces incident response time, and improves governance over alerting configurations. A documentation fix in google_monitoring README updates parameters for production and non-production environments (period, selected_regions, alignment_period) and revises cost examples to reflect current usage, reducing misconfigurations and improving cost estimations. Overall impact: stronger monitoring coverage, lower deployment risk, and improved transparency for stakeholders. Technologies/skills demonstrated: Terraform module development, Google Cloud Monitoring integration, IaC best practices, and documentation maintenance.
